My Delphi 2010 is sick

[WojTec]

So, I have custom constructor, I'm setting components in this constructor, all what happen later depend on these settings - and working, till I add this check box or combo box (I tried both).

For example I'm drawing gradient, in method I'm using cbPath.Checked - working.
When I add this condition then stop working

Code:

---------------------------
Debugger Exception Notification
---------------------------
Project x.exe raised exception class EAccessViolation with message 'Access violation at address 0062DCF7 in module 'x.exe'. Read of address 00000000'.
---------------------------
Break   Continue   Help   
---------------------------

Code:

---------------------------
Debugger Exception Notification
---------------------------
Project x.exe raised exception class EReadError with message 'Error reading edtSteps.SpinOptions.MinValue: Access violation at address 0062DCF7 in module 'x.exe'. Read of address 00000000'.
---------------------------
Break   Continue   Help   
---------------------------

This behaviour is completely nonesense for me...
